Poll: Support for same-sex marriage in US has flattened

Key Points:

• Support for same-sex marriage in the U.S. has plateaued after decades of growth, with overall approval dropping slightly to 65% in 2024 from 71% in 2022 and 2023, largely due to declining acceptance among Republicans.
• Only 37% of Republicans now support legal same-sex marriage, and 35% view gay and lesbian relations as morally acceptable, while Democrats and independents maintain stable, majority support for both.
• The partisan divide on LGBTQ+ issues is reflected in recent state-level legislative efforts, with some states pushing to ban same-sex marriage and others introducing protective measures, despite nationwide recognition since the 2015 Supreme Court ruling.
• Acceptance of transgender people is also declining, with about 40% of Americans viewing gender transition as morally acceptable, down from nearly 50% in 2021, amid ongoing political battles over transgender rights and related policies.
• The Gallup poll was conducted in May 2024 with 1,001 U.S. adults, carrying a margin of error of ±4 percentage points, highlighting subtle but notable shifts in public opinion on LGBTQ+ issues.
